Portulaca plant named ‘DPORMPZPUP’

ABSTRACT

A new and distinct cultivar of Portulaca plant named ‘DPORMPZPUP’ is disclosed, characterized by large, vivid purple flowers, dark green foliage, and a controlled, semi-trailing habit. The new variety is a Portulaca, typically produced as an ornamental plant.

Latin name of the genus and species: Portulaca oleracea.

Variety denomination: ‘DPORMPZPUP’.

BACKGROUND OF THE INVENTION

The new Portulaca cultivar is a product of a planned breeding program conducted by the inventors, Pazit Sharoni, Amir Zuker and Gavriel Danziger in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce useful new Portulaca varieties for ornamental horticultural production. The open-pollination resulting in this new variety was made during 2016.

The seed parent is the unpatented, propriety variety referred to as Portulaca ‘PT-16-1441’. The pollen parent is unidentified. The new variety was discovered in July of 2017 by the inventors in a group of seedlings resulting from the 2016 open pollination, in a greenhouse in Moshav Mishmar Hashiva, Israel. After selection of the new variety, extensive confidential testing has been performed to determine and define the desirable characteristics of the new variety.

Asexual propagation of Portulaca ‘DPORMPZPUP’ was performed by vegetative basal cuttings during August of 2017 at a research greenhouse in Moshav Mishmar Hashiva, Israel.

SUMMARY OF THE INVENTION

The cultivar ‘DPORMPZPUP’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DPORMPZPUP’. These characteristics in combination distinguish ‘DPORMPZPUP’ as a new and distinct Portulaca cultivar:

-   -   1. Controlled, semi-trailing habit.     -   2. Large flowers.     -   3. Vivid purple flower color.     -   4. Dark green foliage.     -   5. Freely branching habit.

PARENT COMPARISON

Plants of ‘DPORMPZPUP’ are similar in some horticultural characteristics to the seed parent. The new variety, however, differs in the following:

-   -   1. Flowers of the new variety are solid, vivid purple; flowers         of the seed parent are dark pink and white.     -   2. Flowers of the new variety are more open and nearly flat;         flowers of the seed parent are more conical to funnel-shaped.     -   3. Flowers of the new variety are larger than those of the seed         parent.

Comparison with the pollen parent is unavailable, as this variety resulted from an open pollination.

COMMERCIAL COMPARISONS

Plants of ‘DPORMPZPUP’ are similar in some horticultural characteristics to the variety Portulaca ‘Nano Purple’, unpatented. The new variety, however, differs in the following:

-   -   1. This comparator has a more compact and dense habit than         ‘DPORMPZPUP’.     -   2. The flower color of this comparator is bright pink with a         yellow eye; flowers of ‘DPORMPZPUP’ are solid, vivid purple.     -   3. Foliage color of this comparator is brighter green than         foliage of ‘DPORMPZPUP’.

Plants of ‘DPORMPZPUP’ are similar in some horticultural characteristics to the variety Portulaca ‘Pazzaz Bright Purple’, unpatented. The new variety, however, differs in the following:

-   -   1. Foliage color of this comparator is brighter green than         foliage of ‘DPORMPZPUP’.     -   2. ‘DPORMPZPUP’ produces larger flowers than this comparator.     -   3. ‘DPORMPZPUP’ produces a brighter purple flower than this         comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DPORMPZPUP’ at about 8 weeks of age, grown in a 19 cm pot.

FIG. 2 illustrates a close-up view of a typical flower of the new variety.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
